中文摘要:
      经研究表明,红石金矿区黄铁矿晶形完好者主要呈立方体{100}和五角十二面体{210}以及它们的聚形.黄铁矿中S/Fe值大于理论值1.148,表明红石金矿是在相对较高的硫逸度及饱和度、较富硫的介质环境下形成的.黄铁矿单矿物的热电动势测定表明红石金矿有四种导型的黄铁矿:P型、N-P型、P-N型、N型.黄铁矿热电系数与温度关系的图解表明,矿区黄铁矿的形成温度为50~385℃,反映出黄铁矿具有多期多阶段的特点,并与红石金矿多阶段的成矿特点一致.黄铁矿的晶胞参数(平均为5.4246Å)较理想值(5.4176Å)偏大.显示出低温条件下黄铁矿的晶胞参数标型.黄铁矿的微量元素标型特征也显示红石金矿为浅成成因.
英文摘要:
      The crystal forms of pyrites of Hongshi gold Deposit are cubic, pyritohedron and their combinations. The S/Fe value is bigger than the theoretical value. This indicates that this deposit is formed in higher sulfide fugacity and saturability. The pyroelectricities of pyrite are P, N-P, P-N, N type. The relationship between pyroelestric coefficient and temperature shows that the pyrite of this deposit is formed at 50-385℃. The unit cell parameters of pyrite are larger than the mean value. The unit cell parameters of pyrite are larger than the mean value. The trace elements of pyrite also show that Hongshi Gold Deposit is epithermal.
